Introducing Bulk Email Verification

June 27, 2026

Upload a CSV, hit Start, and get back a clean list — thousands of emails verified in minutes.

Bulk Email Verification

If you have a list of emails — from a newsletter signup, a CRM export, or a lead gen campaign — Bulk Verify is your fastest path to a clean, deliverable list.

How It Works

  1. Go to Bulk Verify in your dashboard
  2. Click Add List and upload a .csv file (one email per row)
  3. Review the email count — credits are only charged when you click Start Verification
  4. Watch real-time progress as Mailtrix works through your list
  5. Download results when complete — filter by Valid, Invalid, Risky, Catch-all, or Unknown

Download Options

Once a job completes, you can download:

FilterUse case
All resultsFull audit of your list
Valid onlyYour safe-to-send list
Invalid onlyEmails to remove
Risky onlyEmails to review manually
Catch-allDomain-level filtering

Queue System

Jobs are processed in order. During high traffic, you'll see your position in the queue. The page updates automatically — no need to refresh.

Credit Refunds

If a job fails for any reason, all credits are automatically refunded to your account.
